The best route around Erhai Lake

Erhai Lake was called Kunming Pool, Hull River and Ye Yuze in ancient times. Erhai Lake is named because it looks like a human ear. Erhai Lake is the second largest freshwater lake in Yunnan Province, located in Dali Prefecture, Yunnan Province. Cangshan Lake and Erhai Lake are interdependent. Erhai Lake originates from Chibi Lake in Eryuan County, with a total runoff area of 2,565 square kilometers, a length of about 42.58 kilometers, a maximum width of 9.0 kilometers from east to west, an area of about 25 1 square kilometer, a storage capacity of 3 billion cubic meters, an average water depth of about1.5 meters and a deepest depth of 20 meters.

Erhai Lake was formed in the early Pleistocene, and was originally a shallow lake. In the middle and late Pleistocene, the basin sank deeply and the lake surface expanded, connecting with Gudengchuan Lake in the north and Guyi Lake in the south in series. After Holocene, it experienced crustal subsidence and sedimentary filling. Then, as the delta developed into a lake, Fengyi Lake disappeared and Dengchuan Lake separated, forming today's lake shape.
